HENRY M. HUMPHREY, OF PLAINFIELD, NEW JERSEY.

PACKAGE FOR PERCOLATING COFFEE.

SPECIFICATION forming part of Letters Patent No. 634,349, dated October3, 1899.

Application filed February 7, 1899. Serial No. 704,801. (No model.) i

To all whom it may concern.-

Be it known that I, HENRY M. HUMPHREY, of Plainfield, in the county ofUnion and State of New Jersey, have invented a new and Improved Packagefor Percolating Coffee, of which the following is a full, clear, andexact description.

The object of my invention is to provide a porous or percolating bag forcoffee and a means for normally sealing the bag at the mouth, but to soconstruct the sealing device that a portion of the mouth of the bag maybe opened and the said sealing device be employed for suspending theopen bag within a pot or other receptacle in which coffee is to beprepared.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar charactersof reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of the improved percolating-package andthe device employed for sealing the mouth of the package, the mouth ofthe package being shown closed. Fig. 2 is a view similar to Fig. l, a

portion of the mouth of the package being opened and in position toreceive liquid. Fig. 3 is a perspective view of the improvedpercolating-bag, illustrating the sealing device as formed into a hookfor the purpose of supporting the bag with its mouth open in areceptacle; and Fig. 4: is a vertical section through a receptacle inwhich coffee is to be made and a section through the percolatingbagsupported within the receptacle by means of the hook formed as shown inFig. 3.

The body A of the bag is preferably made from a coarse or porousmaterial, such as cheese-cloth, or any material through which water mayreadily pass. The shape of the bag A, although shown as rectangular, may

be changed, and it is closed on three edges, the month only of the bagbeing open when said bag is completed. After a sufficient quantity ofground coffee has been placed in the bag the mouth of said bag is closedby a sealing-plate 10, and this plate is provided with a flange 11,whichis bent over the mouth of said bag, engaging the material of the bag ateach outer side edge of its mouth. The flange 11 of the sealing-plate iscrimped, compressed, or'ot-herwise forced in close contact with thematerial of the bag, so as to hold the mouth closed, and the flange 11of the sealing-plate is provided with a transverse depression orindentation 12, placed usually between the center of the flange and oneend,

and in attaching the sealing-plate to the mouth portion of the bag Athat portion of the flange and sealing-plate between the indentation 12and the adjacent end is so firmly fixed on the bag that said bag cannotreadily be separated from the sealing-plate between said two parts; butthe flange and sealing-plate between the indentation 12 and the oppositeor farthestreinoved end of the sealing-plate is attached to the bag withsufficient force only to keep the mouth closed, so that when it isdesired to make drip-coffee a portion of the mouth of the bag may beseparated from the sealingplate, as shown in Fig. 2, the separation ofthe mouth of the bag from the plate being between the indentation 12 andthe end of the plate farthest removed therefrom. The separated portionof the sealing-plate is next bent upon itself in a downwardly direction,forming a hook 10, and when the plate is thus bent, as shown in Fig. 3,a portion of the mouth of the bag is held open, and the bag may besupported within a receptacle B, as shown in Fig. 4, bypassing the hook1O over the upper edge of the receptacle, the bag be ing suspendedwithin said receptacle. Water is then poured into the bag and permittedto percolate through the coffee in the bag and from the bag into thereceptacle.

Under this construction of coifee-package it is evident that the bag orpackage maybe placed in the coffee-pot without opening the mouth of thepackage and the strength of the coffee be withdrawn by properly heatingthe fact, a strip of metal may be employed of such width only as toclamp opposite sides of the package or bag.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A coffee-package, and a sealing device for themouth of said package, said device hein g pliable and securely attachedto the In outh portion of the package for a portion of the length ofsaid mouth.

2. Acoffee-package, consisting ofa bag constructed of a porous material,and a sealing plate or strip of a pliable material, the sealing plate orstrip being provided witha flange and With a division between its ends,said plate or strip being adapted for clamping engagement with the mouthportion of the bag, a positive attachment between the bag andsealing-plate occurring only between the said division and contiguousend of the plate or strip, substantially as described.

3. A coffee-package consisting of a porous bag, a sealing plate or stripfor the mouth of the bag, adapted to extend over said month, having adivision between its ends, the said plate or strip being attachedthroughout its length to the mouth portion of the bag, the bag beingadapted to be disengaged from the sealing plate or strip between one endthereof and said division, and positively secured to the plate or stripbetween its division and the opposite end of the plate or strip.
